Unraveling the intersection of sleep disorders and erectile dysfunction: Outcomes from two EPISONO editions.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundThere is growing interest in the relationship between sleep disorders and erectile dysfunction. We present the results from a 2015 follow-up study in relation to the 2007 edition of Epidemiologic Sleep Study (EPISONO), a population-based sleep study conducted in São Paulo, Brazil, and from the 4th edition of EPISONO (2018), with respect to the incidence and prevalence of erectile dysfunction, and the associated risk factors. We hypothesized that the presence of erectile dysfunction would be associated with total testosterone levels and obstructive sleep apnea in both longitudinal and cross-sectional analyses.
methodThe participants underwent polysomnography, and testosterone assays were performed. They also completed a range of health questionnaires. The sample comprised men aged 20‒80 years. In the longitudinal analysis, incidence the (N = 256) and prevalence (N = 300) of erectile dysfunction were calculated, and a generalized estimating equation model was constructed. For the analysis of the data from 2018, prevalence (N = 314), binomial logistic regression, and mediation-moderation models were calculated.
resultsAn overall incidence of 10.55% of erectile dysfunction was found in the follow-up, which was higher in men older than 50 years. In the longitudinal model, older age (odds ratio = 1.09), more depression symptoms (odds ratio = 1.05), and low total testosterone concentration (odds ratio = 2.69) were significant predictors of erectile dysfunction. Psychological well-being (World Health Organization Quality of Life) was a predictor of lowered odds of having erectile dysfunction (odds ratio = 0.87). In EPISONO 2018, a 20.06% general prevalence of erectile dysfunction was identified, and this prevalence was higher in age groups over 50 years. The odds of having erectile dysfunction were increased by age (odds ratio = 1.07), and the psychological domain of World Health Organization Quality of Life was associated with lowered odds of having erectile dysfunction (odds ratio = 0.65). Mediation models revealed a statistically significant mediation of apnea‒hypopnea index between the effect of age on total testosterone. The model that included age as the independent variable, apnea‒hypopnea index as a mediator and erectile dysfunction as the outcome resulted in significant effects of age but not apnea‒hypopnea index.
conclusionsThis study highlights the importance of aging, psychological quality of life, testosterone concentration, and depressive symptoms in the context of erectile dysfunction. An association between obstructive sleep apnea and erectile dysfunction was observed, but it was not independent of age. The longitudinal results emphasize that, besides aging, these are modifiable factors that can be the subject of interventions to mitigate the development of erectile dysfunction over time.
